Can git branches be listed with numbers?

Question

I was wondering if anyone had built a script or had a way to list git branches with numbers so that instead of this (preferably in bash)

feature/myusername/ID-1111-my-branch-name
feature/myusername/ID-2222-my-branch-name
feature/myusername/ID-3333-my-branch-name
feature/myusername/ID-4444-my-branch-name

I could get a list like this (or similar)

#1 feature/myusername/ID-1111-my-branch-name
#2 feature/myusername/ID-2222-my-branch-name
#3 feature/myusername/ID-3333-my-branch-name
#4 feature/myusername/ID-4444-my-branch-name

Then checking out a branch would be as easy as

git checkout #4

Answer 1

This sounds like it would be quite easy to create. A simplistic implementation could work with two one-line scripts/aliases.

git-lbr (list branch):

#!/bin/bash

git branch --no-color | cat -n

git-coid (checkout id)

#!/bin/bash

git checkout $(git lbr | egrep "^\s+$1\s+" | egrep -o '\S*$')

But that's a simplistic implementation with no error handling for cases with missing input / non-numeric input / out of range branch ids.

Example of use:

$ git lbr
     1    branch_42
     2    feature/super-feature
     3    foo/bar
     4  * master

$ git coid 1
Switched to branch 'branch_42'
Your branch is up-to-date with 'master'.

Answer 2

For Git Bash on Windows, I edited the .gitconfig file in my user directory to have the following section:

[alias]
    lbn = !git branch | cat -n
    cobn = "!f() { branch_name=$(git branch --format='%(refname:short)' | head -n $1 | tail -n 1); git checkout $branch_name; }; f"

This may not be the most sophisticated approach, but it worked for me:

$ git lbn
     1    bugfix/1234_CrashInAboutScreen
     2    feature/feature1
     3    feature/feature2
     4  * master

$ git cobn 2
Switched to branch 'feature/feature1'

Like Alderath's answer, mine is also a simple implementation without input validation or error handling.
